Caller type: Scammer/Fraudster
It was a total scam. A guy sounding like an Indian telling me that I defrauded the IRS of almost $4,000. He told me that I was about to get arrested by my local sheriff unless I pay the amount in full. I asked him to send me some paper documents, to which he responded that all the documents were in court in Washington DC. I laughed out loud and he quickly hung up.
